What is a Mattress Coil Gauge?
Coil gauge is the measurement of the thickness of the wire used to make a mattress coil. "Gauge" is a technical term commonly used to measure the thickness or diameter of something. From electrical wires, to shotgun shells, to mattress coils, the gauge is a measurement of the thickness of that component.
Shopping for a mattress can be confusing. With all of the technologies and terminology you run into while doing research, it can be difficult to know what is important and what is not. Coil gauge is one of those terms that you will see or hear as you shop for a new mattress. The coil gauge of a mattress measures the thickness of the coils inside. Mattress coil gauges most commonly range from 12 to 15. Contrary to what we are used to, a higher gauge number means a thinner coil wire, and a lower number means a thicker gauge.
Lower coil gauges (thicker wires) result in a firmer spring, while higher coil gauges (thinner wires) create a more gentle spring. If you enjoy a mattress that is more forgiving, then you should look for a mattress with a coil gauge above 14. If you like a very firm level of comfort, then you generally want a mattress with a gauge of 13 or lower. Coil gauge can also be a signal of the durability of the mattress. Typically, mattresses with a lower coil gauge have a longer durability than mattresses with a higher coil gauge because the thicker wire won't wear out as fast. However, most people replace a mattress long before the coil system wears out, so coil gauge isn't the primary determining factor of a mattress' durability.
Other Important Factors
While coil gauge can give you some information about how a mattress feels, it shouldn't be your only focus as you try to find the ideal mattress. The comfort a mattress provides comes from a combination of the coil system and comfort materials. A mattress with a low coil gauge could have a pillow top or euro top and thus, feel a lot softer than some other mattresses with the same coil gauge. At US-Mattress, you can find mattresses at every comfort level and with the most common coil gauges.
